Default 95 SSEI Random stalling

My car runs good most of the time, but I ran into a problem like two weeks after I bought it. The car will randomly stall while driving...

I replaced Fuel pump, thinking that might be the problem but apparently not. I was reading on these forums and wondering if it could be the crank sensor, and is it expensive, or is there a price range somebody could tell me. If not, what are some other things that makes it randomly stall.
I dont know if this means anything but, it always stalls when I have a little more of a quarter of gas in my tank. I pull over , I usually have to wait 5-10 minutes, maybe a bit more until it starts again.

Help would be great...

Hi, I just had this problem with my 95 SE. I replaced the Throttle position sensor, Air idle control selenoid, fuel pump, fuel filter, and crank position sensor. I finally replaced the PCM and that solved the problem. My problem started off just like yours, however, it increased in frequency until just wouldnt stay running. Are you having a difficult time starting the car occasionally? The crank position sensor is not to expensive, bout 100 bucks, so is the PCM from Checker/Kragen.. The PCM will take about half an hour to change even for the beginner. but the crank position sensor will take several hours and you need several special tools. You can test the crank position sensor with an ocsilliscope with the car cranking/running. As far as the PCM, I could not get a link with a code reader. That should have been my first clue. Good luck, let me know which way you intend to go. I have suggestions on both. Hope this helps.

First off - welcome to the club. Could you add your year and trim level in your profile? We can help you out a lot better if we know that information.

Do you get service engine soon, or check engine light? If so, get it scanned and let us know what the codes are.

It'* not likely to be the crank sensor, as that won't stop the engine once it is running. There are many things that could cause it to stall. If it wasn't for it always being when the fuel was on the low side, I'd lean toward the ICM or PCM, but we'd need to trouble shoot some more before we decided on that. When you're trying to start it after it dies, can you hear the fuel pump come on for a few seconds?

Well, about two months, for like a couple days, my car had lots trouble starting, I remember I would be getting some gas at the gas station and it wouldnt start so that I can get out of the gas pump lane.

I believe I fixed the problem thought, My terminals were really nasty and corroided, therefore I cleaned that off, and it starts good most of the time.

I have no lights come on, like engine or such, but when it stalls , the typical dinging light comes on, with no power to the brakes or the steering.

Hmmm, I was looking around, and notice you guys talking about pcm, Ill have to check into it

The first things to do are the free items.

Clean your battery connections like you did, but at both ends. Clean all the grounds. Remove coils/ICM, clean under it and the mounting plate. All these are possible trouble spots.

Also..check your driverside carpet for wetness. There are grounds by the door sill that can give you problems if they have gotten wet and corroded.

Then, notice any similarities or things the car is doing when it dies. Once you get that pinned down, some that have needed to replace the computer will be able to get a better idea if you issues sound correct.

While you're cleaning things, you may want to clean the other end of each cable, too. Also, clean the ground where the ignition control module attaches to the engine, remove and reinsert the multi-connector plug on the end of the module, and clean-up where the coils attach to that module. A little dielectric grease on the connections can help prevent corrosion.

If the PCM is intermittent, sometimes a light tapping on it while the car is running will cause it to stall.

Do you hear the fuel pump prime when you first turn on the key? How does the starter sound? Normal speed, or slow?

And get your battery tested. If the terminals were that cruddy, the battery itself might be suffaering from old age.

Well, the fuel pump is ok, its brand new, but just to be sure, I checked and turn the key, and I can hear the fuel pump whirling.....

Where exactly is a pcm on 95, Im gonna try that method of tapping it, and seeing what happens?

Before you go with your PCM, do the ICM/Coil/Bracket cleaning and all batter cables at each end.

This is a typical cause of stalling. Battery cables have bit quite a few here, and your symptoms are perfectly in line with that being the cause.

And check that driverside floor for wetness...

One member had to kick is car to keep it running to get home.

Lots of more possible free things to look at before you spend on a pcm that might not fix the problem. We know the 95 pcm is flakey at best..but experience says to do the other things first.
